gpio: Add gpio_request_by_line_name()

Add support for the upstream gpio-line-names property already described
in the common GPIO binding document[1]. The ability to search for a line
name allows boards to lift the implementation of common GPIO behaviours
away from specific line indexes on a GPIO controller.
